(a) In a child custody proceeding, each party, in its first pleading or in an attached affidavit, shall give information, if reasonably ascertainable, under oath as to the child’s present address or whereabouts, the places where the child has lived during the last five years, and the names and present addresses of the persons with whom the child has lived during that period. However, where there are allegations of domestic violence or child abuse, any addresses of the party alleging violence or abuse and of the child which are unknown to the other party are confidential and may not be disclosed in the pleading or affidavit. The pleading or affidavit must state whether the party: (1) Has participated, as a party or witness or in any other capacity, in any other proceeding concerning the custody of, or visitation with, the child and, if so, identify the court, the case number, and the date of the child custody determination, if any. (2) Knows of any proceeding that could affect the current proceeding, including proceedings for enforcement and proceedings relating to domestic violence, protective orders, termination of parental rights, and adoptions and, if so, identify the court, the case number, and the nature of the proceeding. (3) Knows the names and addresses of any person not a party to the proceeding who has physical custody of the child or claims rights of legal custody or physical custody of, or visitation with, the child and, if so, the names and addresses of those persons. (b) If the information required by subdivision (a) is not furnished, the court, upon motion of a party or its own motion, may stay the proceeding until the information is furnished. (c) If the declaration as to any of the items described in paragraphs (1) to (3), inclusive, of subdivision (a) is in the affirmative, the declarant shall give additional information under oath as required by the court. The court may examine the parties under oath as to details of the information furnished and other matters pertinent to the court’s jurisdiction and the disposition of the case. (d) Each party has a continuing duty to inform the court of any proceeding in this or any other state that could affect the current proceeding.
